In car charger output rating, USB connection

A question in respect of in car chargers – I have a double lighter socket.

I have a TomTom SatNav with a genuine TomTom USB connection from the cigarette lighter to the TomTom.

I need access to an in car charger also for a Samsung Galaxy S4 phone at the same time.

1)The TomTom in car charger is rated as being having output 5.0v 2.11A.

2)I also have a spare TomTom in car charger rated at 5.0v 1.2A

3)The supplied mains charger for the S4 indicates an output of 5.0v 2.0A.

4)The supplied mains charger for my Galaxy S3 displayed an output of 5.0v 1.0A.

Do I have a problem in using any of the above which are all USB with the S4 excepting that the charging time will be vary for each, relating to its output?

I would not expect you to have any problems with in-car charging of any of your mentioned items.
